I think my electric fuel pump has failed.
1-I don't hear the pump when I turn the key on.
2- The fuse is not blown.
3- My Optima trunk mounted battery has 12.43 volts.
4- I don't see fuel entering the FIT throttle body.

What am I missing ? Is there something else I need to check ?

Measure the voltage at the pump when you turn the key on. Sounds like you have EFI so it could be ECM or fuel pump relay etc

Thank you, I'll let you know what I find. After 10 years this is the first issue I've had so I'm lucky I guess.
